IPC: D06P/
Filed: 1956-10-12
Abstract: Cellulosic textiles are dyed or printed by applying, locally or otherwise, an aqueous solution of a heterocyclic compound containing at least one grouping <FORM:0825771/IV(c)/1> in the heterocyclic ring obtainable by reacting a compound containing an ionogenic solubilizing group and an amino or mono-substituted amino group with a heterocyclic compound, e.g. cyanuric chloride or 2:4:6-trichloropyrimidine, containing at least twice the grouping <FORM:0825771/IV(c)/2> also applying, before, together with or after the heterocyclic compound, an aqueous solution containing 0.1-3.0% by weight of an acid-binding agent such as sodium or potassium hydroxide, sodium carbonate or bicarbonate, trisodium phosphate or sodium metasilicate, and finally applying a diazonium salt containing an electronegative substituent.  Suitable heterocyclic compounds are azo, anthraquinone, nitro, phthalocyanine and indigoid dyestuffs containing the above-specified heterocyclic ring, and numerous examples are given.  Dyestuff intermediates such as 2-naphthylamino - 6 - sulphonic acid, 1 - amino-8 - hydroxynaphthalene - 3:6 - disulphonic acid, 2 - methylamino - 5 - hydroxynaphthalene - 7 - sulphonic acid and 2 - amino - 8 - hydroxynaphthalene - 6 - sulphonic acid, which have been reacted with cyanuric chloride or 2:4:6-trichloropyrimidine, may also be employed as the heterocyclic compound.  The solution of the heterocyclic compound may contain sodium chloride, sulphate or alginate, urea and soluble alkyl cellulose ethers, and when employed for printing may contain other thickeners such as starch or locust bean germ.  Specified diazonium salts which may be applied from aqueous solution by padding or printing are the diazonium salts of 2:4-dinitroaniline, 41-nitro4 - amino - 2 : 5 - dimethoxyazobenzene, orthanilic acid, 2 - amino - 4 - methoxy - 5 - methyl-21 - chloro - 41 - nitro - azobenzene, 4 - amino-3 - methoxyazobenzene, 21 - chloro - 41 - nitro-2 - amino - 4 - methoxy - 5 - methylazobenzene, 21 - nitro - 2 - amino - 41 : 5 - dimethyl - 3 - methoxyazobenzene, 21 : 61 - dichloro - 41 - nitro - 4-amino - 2 : 5 - dimethoxyazobenzene, o - nitroaniline, 1-aminoanthraquinone and 4-amino-21 : 5 - dimethylazobenzene. Pattern effects may be obtained by printing on the heterocyclic compound, then applying a resist paste to overlap the pattern partly and finally applying the diazonium salt, or instead of applying the resist paste, a paste of the diazonium salt may be applied partly to overlap the pattern.
